Abstract
AIM:
To evaluate the efficacy and safety of Traditional Chinese Medicine (TCM) in the treatment of Helicobacter pylori (H. pylori) infection.
METHODS:
We electronically and manually searched electronic databases, references lists and conferences compilations, and included all randomized clinical trials comparing the treatment of H. pylori using TCM with proton pump inhibitor or colloidal bismuth subcitrate-based triple therapy as controls. The Jadad score was used to assess trial quality, H. pylori eradication rate and the incidence of side effects were taken as outcome measurements, and heterogeneity analysis, meta-analysis and funnel plot analysis were conducted.
RESULTS:
Sixteen trials were included. The Jadad scores of all the trials were not more than 2. Clinical heterogeneity and substantial statistical heterogeneity existed among the trials (P = 0.001, I(2) = 59%) and meta-analysis was not conducted. The average eradication rates following TCM and triple therapy were 72% and 78% and the incidence of side effects were 2% and 29%, respectively. The funnel plot was obviously asymmetric.
CONCLUSION:
Available evidence is not convincing enough to show that TCM has the same efficacy as triple therapy in H. pylori treatment. TCM may be safer than triple therapy. TCM should not be recommended as monotherapy in H. pylori infection.
